I believe the information which session was used last is already present.
There should be no need for a .screen.lastsession file.
Here is a bash script, that looks at the mtime of each socket and
reattaches to the last modified one:

I don&#39;t think screen has the tmux equivalent of hooks...<br>

A) Add this feature to screen<br>

Shouldn&#39;t be too hard I think... just something which writes the sessio=

<br>
B) A heartbeat script<br>
<br>
Create a new (hidden) screen window and run something like:<br>

ession&quot;<br>
<br>

You could possible add something in .screenrc to spawn this<br>
automatically.<br>
<br>
Personally, I think I&#39;d patch screen and contribute the code.<br>
